Answer:

(a).The volume of cube is changing at the rate [tex]450 cm^3/s[/tex]

Step-by-step explanation:

Let x be the side of cube

[tex]\frac{dx}{dt}=6 cm/s[/tex]

We have to find the rate at which  volume of cube changing when edge is 5 cm.

We know that

Volume of cube, V=[tex]x^3[/tex]

Differentiate w.r.t t

[tex]\frac{dV}{dt}=3x^2\frac{dx}{dt}[/tex]

Substitute the values

[tex]\frac{dV}{dt}=3(5)^2\times 6[/tex]

[tex]\frac{dV}{dt}=450 cm^3/s[/tex]

Hence, the volume of cube is changing at the rate [tex]450 cm^3/s[/tex]

answer: 20

in the number line, you can see that the dot on 20 is an open circle. this means that it is not included. so 20 could be one of the answers.

- anything greater than 20 would be an answer.

Answer:

1. V(12) = $ 1200

2. V(20) = $ 4800

Step-by-step explanation:

The following data were obtained from the question:

V(t) = 150 × 2ᵗ/⁴

V(12) =?

V(20) =?

1. Determination of V(12)

Time (t) = 12 years

V(12) =?

V(t) = 150 × 2ᵗ/⁴

V(12) = 150 × 2¹²/⁴

V(12) = 150 × 2³

V(12) = 150 × 8

V(12) = $ 1200

2. Determination of V(20)

Time (t) = 20 years

V(20) =?

V(t) = 150 × 2ᵗ/⁴

V(20) = 150 × 2²⁰/⁴

V(20) = 150 × 2⁵

V(20) = 150 × 32

V(20) = $ 4800

Answer:

105

Step-by-step explanation:

180 - 140 = 40

180 - 145 = 35

35+ 40 = 75

180 - 75 = 105

a = 5

Answer:

105

Step-by-step explanation:

interior angle next to 145 is 180-145=35

interior angle next to 140 is 180-140=40

angle a= 180-35-40=105

Answer:

y = 12665 (100⁻¹)  + b

Step-by-step explanation:

To model this relationship, you're to write the equation of a line; in the form

y = mx + b

Now let y represent the full coupon value,

mx represent the amount spent by Hellen and her sister

and b, the change that's left on the coupon.

So, the summary of Hellen's transaction is:

$85.2 became $(85.2 - 12.78) which is  =  $72.42

The summary of her sister's transaction is:

$63.8 became $(63.8 - 9.57) which is  =  $54.23

So   y - (72.42 + 54.23) = b

y - 126.65 = b

y = 126.65 + b

Separating m from x in mx, you have

y = 12665 x 1/100  + b

y = 12665 (100⁻¹)  + b

Where m = 12,665   and x = 100⁻¹

a) the graphs of a equation are parallel

Answer:

y=-2/3x+3

Step-by-step explanation:

The y intercept is (0,3)

another point on the graph is (3,1)

Answer:

the slope is 1

Step-by-step explanation:

Answer:

1

Step-by-step explanation:

Slope = change in y / change in x

Slope = 1 / 1 = 1

Answer:

The angular speed of the blade is of 166.67 rad/min

Step-by-step explanation:

The velocity, is given by the following equation:

[tex]v = rw[/tex]

In which r is the radius and w is the angular speed.

We use this relation to solve this question;

We have that:

[tex]v = 1000, r = 6[/tex]. We want to find w. So

[tex]v = rw[/tex]

[tex]1000 = 6w[/tex]

[tex]w = \frac{1000}{6}[/tex]

[tex]w = 166.67[/tex]

The angular speed of the blade is of 166.67 rad/min

Answer:

$27.69

Step-by-step explanation:

Given

Monthly budget (See attachment)

[tex]Month = 4\ weeks[/tex]

[tex]Week = 40 \ hour[/tex]

Required

Determine the closest hourly wage

From the attachment, the monthly budget is:

[tex]Budget = \$ 4430[/tex]

First, we calculate the closest weekly earnings.

Since a month = 4 weeks.

Then

[tex]Weekly\ Earnings = \frac{\$4430}{4}[/tex]

[tex]Weekly\ Earnings = \$1107.5[/tex]

Next, we calculate the hourly earnings:

Since 1 week = 40 hour

Then

[tex]Hourly\ Earnings = \frac{\$1107.5}{40}[/tex]

[tex]Hourly\ Earnings = \$27.6875[/tex]

From the list of options, the closest is: $27.69

Answer: No.

Step-by-step explanation: This is because the sum of 2 side lengths has to be greater than the remaining side length. 3+6 is not greater than 9, so a triangle cannot be formed.
